The Rev. Al Sharpton began his new career as an official MSNBC talk show host on Monday by telling viewers not to expect James Brown.

“I’m not going to be a robotic host reading the teleprompter like a robot,” he said. “Nor am I going to come in here and do the James Brown and do the ‘electric slide’ to prove to you that I’m not stiff,” he added, waving his arms in a rough approximation of a dance move. “I’m going to say what I mean and mean what I say.”

And that may be the problem with Mr. Sharpton’s cable news pulpit: what he means to say is in lockstep with every other MSNBC evening program, making the stretch between 6 p.m. and 11 p.m. a nonstop lecture on liberal values and what is wrong with the Republican Party.
